正交试验、统计分析在纺纱质量控制中的应用

Application of Orthogonal Test and Statistical Analysis in Spinning Quality Control

为了使纺纱企业的内部管理做精、做细,将终端产品做实,从介绍正交试验法和数理统计着手,以梳棉机系列工艺试验优化为例,阐述正交试验、统计分析在纺纱质量控制中的应用;从其方法选择、工具运用、数理分析及成效验证等方面,详细说明纺纱厂质量控制方法。指出:科学运用统计工具收集有效的试验数据并进行数理分析,对纺纱质量管理和控制至关重要;纺纱企业要结合自身特点,精细化内部管理,才能获得发展空间。

To do a fine job with meticulous attention in internal management of a spinning enter prise,and to make the terminal products second to none, sampling the optimization of series process test of the card starting with the introduction of orthogonal experimental method and mathematical statistics,description is done to the orthogonal test and statistical analysis of ap plication in spinning quality control including the choice of the method, tools, mathematical per formance analysis and verification to the series of experiments of the card in a detailed description of spinning quality control method. It is pointed out that the scientific use of statistical tools to effectively collect the test data and the mathematical analysis is crucial to spinning quality management and control. Spinning enterprises which need some development space must combine their own characteristics and fine internal management.
